The M1 blank is 4 pin, the M10 blank is 5 pin. The actual keyway name is something different than either number, but not being a locksmith, I am not sure what it is.
I will grab a couple of your older locks and pick them for comparison of the updated M1 lock cylinder. It has been a while since I last picked the Commando locks and my skills have improved since then. Therefore to make a more accurate evaluation, will pick a couple of them, then get back and post the comparison.
@Evan - Thank you for correcting my misunderstanding of the ILCO key number.I still have tons to learn. That is why my signature still has not changed. I appreciate all the knowledge that so many people here share with me.

Good call Evan. That makes sense--And is the M15 for the 6 pin? I have 25K 4 pin cylinders I haven't used and I think they're not stamped with any designation. I recall a number that specifies a left hand keyway vs right hand as well. I'll check my 4 pin cylinders and report back.
